    Basic, Premium, or Handle Mold?

    We often get asked about the difference between basic and premium molds.

    Basic Molds:

    • Have a wooden box to support the liner.
    • Have holes in the bottom of the wooden mold to push out the liner.
    • Do not have a lid.

    Premium Molds:

    • Have a wooden box to support the liner.
    • Have a clear lid to view soap as it gels and prevent soda ash.
    • Have grooves in the wooden mold box that the lid slides into, creating a seal between the soap and outside air. This is the main method of preventing ash.
    • Have removable sides for easy removal of the liner.

    Handle Molds:

    Handle molds come in basic and premium styles. They provide the ultimate ease of use when making soap. The lip of the liner surrounds the wood mold and keeps it clean. The handles on the liner allow for very easy removal from the mold. 

    However, the sides of the wooden mold box are not removable in the premium style, and the basic style does not have holes in the bottom of the box for removal. This is because you can simply lift up by handles and the liner pops right out! Another benefit of our handle molds is the silicone is thin yet sturdy, make soap a breeze to remove from the liner.

    If you do not gel or cover your soaps, basic molds are best. They can be covered with cling wrap to prevent ash. If you prefer to gel your soaps and want more ease of use, premium molds are ideal. Handle molds offer the best of both worlds in premium and basic styles.

    Mold Sets:

    A mold set is any mold available as a full set. For example, basic molds come with a liner and wood support box and premium molds come with a liner and a box and a lid. Mold sets are all the components you need in a mold at a lower price then buying them separately.

    Slab mold

    Excellent quality! Easy to unmold! Purchased 2 and once I tried I purchased 2 more!


    Super convenient for when I just need to make 2 batches of soap.

    I have 9 molds from 4 different companies

    Hands down, Natures Soap molds out do all other molds. The silicone molds are sturdier then the others and I love the sides that I can lift out to slide my molds out where then are full. I now ONLY buy from Natures soap. The following photo shows you what I get out of 12 pound molds. There are two sets in the photo. I am currently waiting on another mold to be delivered I ordered from Natures Soap/

    I love the 12 pound mold!

    I use these all of the time. I still prefer the old (green) slab mold, but these work just as well! I did notice that they seem to be *slightly* smaller than the older molds, as well, but that might just be from years of use. Overall, a great mold!

    12 Lb. Slab Mold - My New Favorite!!

    I purchased my first 12 lb. slab mold at the end of last year. I had been looking for a slab mold that would give me the same size bars as I was already making. This mold is wonderful! I get 36 perfect bars of soap each time. It is easy to take the liner out with the removable end, very sturdy and easy to clean. I wanted to buy another one almost immediately and they were sold out. I am so happy they were back in stock the other day and I ordered two more. I also ordered an extra liner for each mold. If you are hesitating on trying out the molds from Nurture Soap Don't! What a great investment for my little business.

    I love the versatility of this mold!

    I can get 36 bars of my traditionally sized bars, or I can pour it an inch thick and get 12 tall and skinny bars of a slab design. The silicone is thick, so I have never experienced bowing. This is a sturdy mold that will last me a very long time!

    The best mold

    I finally got my 12lb mold that I've had on my wish list. This makes it easy for me to increase the amount of product I can make. The mold is wonderful. It's not green like my other one but white. It's the best mold to use to make cold process soap.
